[research] How to evaluate agent actions across different tool verifiability levels

Map tools to a verifiability spectrum. Use exact match/regex for CLI/DB tools, execution-based evals for code, and LLM-as-a-judge only as a last resort for UI/DOM interactions.

Journey Context:
A common mistake is applying a single eval strategy \(usually LLM-as-a-judge\) to all agent actions. CLI commands and API calls are deterministic and structurally verifiable; if an agent runs \`git commit -m "fix"\`, you can assert the exact command. Browser actions are stochastic and visually complex. Mixing these without separating them by verifiability leads to flaky evals or false confidence.
